Since the 1960s,endovascular coil embolization has gradually become another treatment for intracranial aneurysms in addition to craniotomy clipping surgery,and in recent years,it has become the preferred method for many neurologists.However,the complexity of intracranial vascular anatomy and the diversity of intracranial aneurysm make the coil embolization alone unable to meet the needs of all intracranial aneurysms.And then some novel materials and techniques emerged,such as coated coils,balloon-assisted embolization,stent-assisted embolization,and covered stents.The principle of covered stents for the treatment of intracranial aneurysms is to place a kind of stents with bio-physical barriers into the parent arteries,while maintaining the patency of the parent artery,thus isolating aneurysms,leading to thrombogenesis inside and finally curing the lesions while maintaining the patency of parent arteries.It has huge advantage in the treatment of wide-necked,huge,dissecting and pseudo aneurysms without important adjacent branch vessels.This article reviews the application situation and the prospects of development of covered stents in the treatment of intracranial aneurysms.

Objective To study the heart rate variability(HRV) and blood pressure variability(BPV) in patients with different grades of hypertension.Methods 120 cases of patients with hypertension,according to 1999 WHO/ISH hypertension diagnostic criteria are:1 hypertension in 40 cases,2 of hypertension in 40 cases,3 of hypertension in 40 cases and 40 cases of normal control group were detected heart rate variability and blood pressure variability.Results HRV was significantly different between the two groups(P <0.05 or p <0.01).The blood pressure increased and HRV tended to decrease.The BPV was significantly different(P < 0.01) between the two groups;the blood pressure increased and the BPV tended to increase.Conclusion The grade of hypertension is related to HRV and BPV.

Objective To evaluate the clinical value of interventional chemotherapy and intravesical instillation for preventing postoperative recurrence and metastasis of cancer in urinary bladder.Methods One hundred and eight patients with urinary bladder cancer were divided into group A and group B.Intravesical instillations after surgical operation were performed in group A (n=52) and combined interventional chemotherapy and intravesical instillations after operation were performed in group B (n=56).The patients were followed up for 1 - 3 years.Results In group A,recurrence occurred in 5 cases (9.62%) within one year,and in 23 cases (44.23%) within 3 years after the operations metastasis developed in 21 cases (40.38%),and 18 cases (34.62%) died.In group B,recurrence occurred in 2 cases (3.57%) within one year,and in 11 cases (19.64%) within 3 years after the operation;metastasis developed in 7 cases (12.50%), and 5 cases (8.93%) died.There were statistical significant differences in recurrence,metastasis and mortality between these two groups (P

Objective To investigate the ability of social cognition in patients with right temporal lobe infarction.Methods Fifteen patients with temporal lobe infarction (TLI) and 20 healthy controls (HC) were examined with the recognition of faux pas and reading the mind in the eyes tasks for assessing the ability of social cognition.Results The TLI group performed significantly worse when compared with the HC group (28.6 ± 6.1,36.4 ± 4.3 respectively) as revealed in the total faux pas-related scores (U =41.00,P ＜0.01).For the control question,there was no significant difference between the TLI group and the HC group (9.86 ±0.35,10.00 ± 0.00 ; U =130.00,P =0.097).In the reading the mind in the eyes task,patients with TLI performed worse than the HC group(17.13 ±6.41,29.75 ±2.07 respectively),and the difference had statistical significance (U =0.00,P ＜ 0.01).But there was no significant difference in gender recognition judgment (30.37 ± 1.16,31.35 ± 1.08 respectively; U =106.00,P =0.129).Conclusions The right temporal lobe involves in social cognition.Moreover,the right temporal lobe not only involves in the verbal related social cognitive processing,but also involves in the no-verbal related social cognitive processing.

Gene chip is a research tool on molecular biology which can detect generous gene expression rapidly.The studies on gene chip of leiomyoma have revealed the changes of gene expression related to cell growth,proliferation,apoptosis,metabolism,angiogenesis,formation of extracellular matrix,cell differentiation and immunity.The article reviews the advance on gene chip of leiomyoma and approaches the pathogenesis of leiomyoma on molecular level.

Background In patients with syphilis,one of the common manifestations is uveitis.However,the lack of understanding on syphilic posterior uveitis may result in misdiagnosis and delayed treatment.Objective This study was to assess ocular clinical features,treatment and prognosis in patients who had latent syphilis and presented with posterior uveitis as the initial symptom.Methods A serial cases-observational study was designed.Twelve patients(19 eyes)who were diagnosed as syphilis from September 2011 to January 2013 were retrospectively analyzed.All patients were characterized by initial posterior uveitis before the final diagnosis.The clinical manifestation,management and prognosis were evaluated and analyzed.All patients were informed of this study and consented with the use of their data for this retrospective study.Results The patients presented with initial clinical signs of acute or chronic posterior uveitis and lacked systemic syphilis symptom.Bilateral posterior uveitis were found in 7 patients and unilateral in 5 patients.The dust-like and grey-white opacification in vitreous was seen by threemirror contact lens in all the patients.Mild hyperemia of the optical disc was found in 10 eyes with the unclear peripapillary boundary.Yellow-white lesions were observed in retinas of 7 eyes and retinal punctuate hemorrhage was in 1 eye.Fundus fluorescein angiography demonstrated fluorescine staining or hyperfluorescence of optic disc in all of the 19 eyes,and fluorescein leakage from vein in 18 eyes,retinal pigment epithelium dye pooling in 6 eyes and cystoid macular edema in 11 eyes.Rapid plasma reagin (RPR) test and treponema pallidum hemagglutination assay (TPHA) were performed and presented positive results in all patients.The visual acuity improved in 19 eyes and partly elevated in 2 eyes following a standard therapy for neurosyphilis was used,including penicillin and/or small doses of glucocorticoid.Conclusions The serological examination for syphilis should be considered for patients with unexplained uveitis.Early diagnosis and prompt treatment are important for the improvement of prognosis in syphilitic posterior uveitis.
